` Assured operating distance: 8 mm
` Assured release distance: 26 mm
` Square design
` Works magnetically
` Switching voltage 24 VDC
` Series connection via PSEN i1 in-

Unit description

The safety switch meets the require­ments of EN 60204-1 and IEC 60204-

1.
The safety switch only complies with
EN 60947-5-3 in conjunction with the
actuator PSEN 2,1-20 and its ap­proved evaluation devices.
The safety switch should only be con­nected to the evaluation devices listed
under "Connections".

Function description

If the actuator is within the response
range, the magnets switch the reed
contacts on the safety switch. If the
actuator is outside the response range
(safety gate open), the reed contacts
on the safety switch will switch.

` When using evaluation devices with

delay-on de-energisation contacts,
please note:
–Delay time ≤ 30 s: Delay-on de-

energisation contacts satisfy the
requirements of category 3 in ac­cordance with EN 954-1 and the
requirements of a PDF with sin­gle-fault tolerance (PDF-S).

–Delay time ≥ 30 s: Delay-on de-

energisation contacts satisfy the
requirements of Category 1 in
accordance with EN 954-1 and
the requirements of a PDF with
designed reliability (PDF-D).

` In the following commissioning cas-

es, check the function that detects
shorts across contacts:
– On evaluation devices with DC

supply voltage: Overall cable re­sistance ≥ 15 Ohms per channel

– On evaluation devices with AC

supply voltage: Overall cable re­sistance ≥ 25 Ohms per channel

– For details of how to perform the

test for shorts across the con­tacts, please refer to the operat­ing manual for the relevant
evaluation device.

Connections

NOTICE

The colour marking for the connection
lead only applies for the cable that Pilz
supplies as an accessory.
The safety switch is shown in an unop­erated condition.

Installation

` The unit can be installed in any po-

sition. However, safety switches

and actuators must be positioned

opposite each other in parallel:

` If possible, do not install the safety

switch and actuator on to ferromag-

netic material. Changes to the oper-

ating distances are to be expected.

In this case, use the spacer availa-

ble under order number 534 310.

` Safety switches and actuators

should only be secured using M4

screws with a flat head (e.g. M4

cheese-head or pan head screws).

Torque setting max. 1 Nm. Use

screws made of non-magnetic ma-

terial (e.g. Messing).

` The distance between two systems

comprising safety switch and actu-

ator must be at least 25 mm.

` Safety switch and actuator

– Keep away from iron swarf

– Do not expose to strong mag-

netic fields

– Do not expose to heavy shock or

vibration

– Do not use as a limit stop

2.2

Adjustment

` The safety switch may only be used

with the corresponding actuator

PSEN 2,1-20.

` Always test the function with one of

the approved evaluation devices.

` The LED lights when the reed con-

tacts are unoperated (safety device

open or safety switch and actuator

wrongly adjusted). The LED is in the

safety switch's N/C circuit. The LED

goes out when the reed contacts

are operated.

` The stated operating distances (see

Technical details) only apply when

the safety switch and actuator are

installed facing each other in paral-

lel. Operating distances may devi-

ate if other arrangements are used.

Note the maximum permitted later-

al and vertical offset (see "Operat-

ing distances" and "Max. lateral

and vertical offset").
